Answer:
Step-by-step explanation:
a = 4
b= 1
c = 2
d =2
Leftside of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 4 *4 + 8 =16 + 8 = 24
No. of P molecules = 2
Right side of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24
No. of P molecules = 2
Answer:
Simplest function is f(x) = 2x - 1
Step-by-step explanation:
When a function has a zero, simply put, that point is where the graph goes through the x-axis. At this point, the y value is 0.
If a function has a 0 of 1/2, that translates to x = 1/2 and also (1/2, 0). That means that y = 0 when x = 1/2.
If x = 1/2 and is a zero, then x - 1/2 = 0 and 2x - 1 = 0 (notice that y = 0 here and solving for x would get you right back to x = 1/2).
The simplest function with a zero of 1/2 is
f(x) = 2x - 1
You know it is true that the zero is 1/2 for two reasons. First one is to set the right side equal to 0 and solve for x.
The second one is to graph the line y = 2x - 1 and see that it goes through the x axis at 1/2 where y = 0.
Answer: $375
Step-by-step explanation:
Given : The probability of winning $100 : P(100)= 0.25
The probability of winning $200 : P(200)= 0.50
The probability of winning $1000 : P(1000)= 0.25
Now, the the expected value of that lottery ticket is given by :-
Hence, the the expected value of that lottery ticket =$375
The rotations that will carry the equilateral triangle in discuss onto itself are;
- 90° counterclockwise rotation about its center P.
- 270° counterclockwise rotation about its center P.
<h3>Which rotations will carry this equilateral triangle onto itself?</h3>
It follows from the task content that the rotation which produces the desired output in which case, the rotation maps exactly unto the equilateral triangle is required.
On this note, when the rotation is 90° and 270° about the center P in which case, the rotation can be clockwise or anticlockwise, the desired result is obtained.

Answer:
35.33
Step-by-step explanation:
The circle with radius 5 has a sector with a central angle of 9/10 pi.
The area of a sector is given as:
where α = central angle of the sector in radians
r = radius of the circle
The area of the sector is therefore:
The area of the sector is 35.33.
